Description
Technical Field
The invention belongs to the technical field of wind power generation, and particularly relates to a wind power blade ice melting and ice inhibiting agent based on an exothermic reaction and a preparation method thereof.
Background
The wind generating set is usually located in high mountains or frontier regions and other regions easy to freeze, and as the perennial average temperature of the regions is low and the outdoor temperature is lower than zero, the blade surface of the wind generating set is easy to freeze, and the wind generating blade in the high-altitude regions with the altitude elevation of 1000-1800 m and forest regions is more serious in the freezing condition in winter. In winter, the blade surface is frozen at the time of abundant wind resources, so that the blade surface directly influences wind power benefits and forms a safety risk for sharing the operation of the unit. Therefore, the problem that the wind power industry needs to solve urgently at present is to prevent and remove the icing of the wind power blade in winter.
The common blade deicing and ice inhibiting technology at home and abroad comprises the following steps: thermal de-icing, coating anti-icing, liquid de-icing, and the like. Thermal deicing usually adopts a mode of introducing hot solution into a cavity arranged inside or arranging a resistance wire inside a blade. The mode of arranging the cavity in the blade can cause stress concentration of the wind power blade, and the mode cannot completely remove the ice layer of the blade; the mode that the resistance wire is arranged inside the blade is complex in process and high in cost, and the heating performance of the resistance wire cannot be guaranteed. The thermal deicing technology has the disadvantages of relatively high energy consumption, additional introduction of a heater for consuming electric energy and reduction of the wind power generation efficiency. The coating anti-icing and deicing method is characterized in that a low-surface-energy substance and a modified surface rough structure are prepared, a multi-agent, porous and multilayer bionic anti-icing and deicing coating capable of actively resisting the lotus leaf surface energy caused by freezing rain, ice and snow disasters can be formed, and the coating is used for dewatering, deicing or reducing icing amount of wind power blades in a high-humidity environment. However, this method still has many problems that passive deicing cannot achieve optimal deicing performance and that deicing materials are not sufficiently durable in practical use. The liquid ice inhibitor is mainly used for spraying the ice inhibitor on the surface of a blade so as to reduce the freezing point of the surface of the wind power blade or change the adhesive force between the surface of the blade and an ice layer.
